Variability Between Perfusion Imaging Software Packages

Studies have demonstrated that estimates of ischemic core and penumbra can vary markedly between perfusion analysis software packages. For example, one recent study indicated that the correlation between estimated ischemic core volume and final infarct volume in patients who achieved early reperfusion differed substantially between 3 commercially available software programs.[18] Therefore, it is important to use a validated software package when selecting patients for late window thrombectomy.
